SPECIFICATION forming part of Letters Patent No. 431,885, dated July 8, 1890.

Application filed September 6, 1889. Serial No. 328,130. (No model.)

To all whom it may concern.-

.lle it known that I, DANIEL FOO-ER, a citi zen of the United States, residing in the city and county of Cape May, State of New Jersey, have invented a new and useful Improvement in Electrical W ater-Alarms, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to electrical wateralarms for use with water columns and gages for steam-boilers, tanks, cisterns, reservoirs, the.

The invention consists of a mechanical apparatus, as herein described, in connection with electrical devices relatively coacting to indicate the position of a volume of water by sounding an alarm.

Figure 1 represents a side elevation of a water-gage, showing my invention applied thereto. Fig. 2 represents a horizontal section of the water-gage, showing a part of my improvement in connection therewith. Fig. 3 represents a view similar to Fig. 1, showing a modification of the invention. Fig. 4 represents a View similar to Fig. 2, showing the modification applied thereto. Fig. 5 represents a detail view in rear elevation of the form of index used in the construction shown by Figs. 3 and 4.

Similar letters and numerals of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the bodyor shell of a water column or gage adapted to be suitably connected to a steam-boiler, tank, &c., said device being illustrated for convenience in showing the application of my improvement, it being understood that the invenion may be applied to other devices. A float B is mounted in said body A, and is attached to a rock-shaft C, having a projecting end for connection therewith of an index D, said mechanism being adapted to indicate the level of the water in the boiler by rising and falling, as will be readily understood.

On the shell or casing A are ai'iixed contact points or posts'l and 2, and to the index D, Figs. 1 and 2, is connected a metallic contact 3,separated from said index by an interposed insulation at. The shell or'casing A is also provided with a binding-post 5, to which is attached a wire 6, running to one pole of a battery 7, and thereby including the said shell or casing A in the electric circuit. The contact 3 has a wire 8 connected thereto and to one post of a bell or signalE, the other post of said bell or signal being connected by a wire 10 to the opposite pole of the battery 7.

The float B lowers when the water in the gage attains a low level, and the index D falls therewith, bringing the contact 3 over the post or point 2, and the circuit is completed through wire 10 to bell E to ring the same, from bell E to battery 7 by wire 10, and from battery 7 back to shell or casing A through wire 6. In the event of high water, contact 3 engages post or point. 1, and the circuit is completed as before. The alarm will be electrically sounded by bell E in both instances, and attention thereby called to the condition of the water in the boiler, tank, 850.

As shown by Figs. 3, l, and 5, the apparatus is modified by the addition of another circuit, including an annuneiator. The contact 3 in this instance is formed in two sections, having wings 15 and 16, separated by insulating material, as shown in Fig. 5, and unitedly insulated from said index, as at l. (See Figs. 1 and 2.) The upper section of said contact is adapted to engage post 1 on shell A, and has a wire 8 connected thereto and running to a post 13 on an annunciator F and actuating the high-water index, the circuit being completed through battery-post 12 of said annunciator, which has a wire 11 attached thereto and running to one of the posts of bell E to ring the same, by wire 10 from the other post of said bell to one pole of battery '7, and from the opposite pole of said battery by wire 6 back to the shell or casing A. \Vhen the lower wing 16 of contact 3 engages a post 2, the circuit is made through a wire 9, connected with the lower section of said contact, rnnnin to the binding-post 1a of annunciator F, to actuate the low-watcrindex, out through battery-post 12 by wire 11 to bell E to ring the same, from bell E by wire 10 to one pole of battery '7, and from the opposite pole of battery 7 back to the shell or casing A. :ly this means an alarm is sounded on bell E in the event of high or low water, and the annunciator F, located in a desirable place, designates whether the water be high or low in the boiler, reservoir, the. The posts or points 1 and 2 Will be located in such position as to being between said contact-points, and a me bein advance of the danger-point of too high tallic contact connected with one pole of the or too low water line. battery and carried by the index, but insu- Having thus described myinvention,what I i lated therefrom, the wire connected with the T5 5 claim as new and desire to secure by Letters other pole of the battery being secured to a Patent, is binding-post on said receptacle separate from A device for the purpose named, consisting the contacts, substantially as described.
